<steev> chrs_: i do
<hno> popolon, normally 912MHz.
<hno> for all A20 chips.
rz2k has quit []
<popolon> hno, thanks
<popolon> as I seen 1Ghz somewhere
<popolon> and a20 Olinuxino also didn't write frequency on it's site
eFfeM has quit [Quit: Leaving.]
<popolon> someone today said me than a7 is crappy
<hno> popolon, Allwinner markets that as 1GHz. just as they market the 1.008MHz of A10 as 1.2GHz...
<popolon> but after the spec, that's a little slower than a8 for int/cpu operation
<popolon> and far faster for float/simd
<hno> popolon, a single core A7 is generally less than a single core A8.
<popolon> yes
<popolon> but not other problems isn't it ?
<popolon> it also use less energy
<popolon> I would like to run it 24/24
<hno> A20 is a dual core A7. which compensates significantly for the per-core performance difference.
<popolon> and on fp will be really faster, if applications are multithreaded so
<popolon> well I will try it :)
<hno> there is reports of A20 at full utilization being significantly hotter than A10 at full utilization, but it also chews a bit more processing/s than the A10.
<hno> getting more done.
<popolon> is there some bench ?
<popolon> I don't want to use it at full power every time
<popolon> in fact, only some times, rarely
<popolon> enough power to some crypted network operation and some really light personal web service is enough for me
<popolon> and some other nework applications
<popolon> +t
<hno> popolon, I haven't run any benchmarks myself. Only seen reports from others.
<popolon> didn't find benchmarks with A10 vs A20
<hno> no links, but most likely in the linux-sunxi mailintlist archives.
<hno> somewhere..
<popolon> oh, thanks I will search for that
<hno> popolon, first stop is linux-sunxi.org
<popolon> does a20 shutdown the second core in low usage mode ?
<popolon> ok thanks ;)
<popolon> I will press the buy button :⁾
<hno> I don''t know how well developer power control is, but the hardware can dynamically enable/disable each core.
<hno> others in #linux-sunxi channel might be able to answer that question if asked during daytime european time.
<popolon> ok, I will add this channel to my list of channels then
<popolon> thanks a lot
<chrs_> steev: hey
<chrs_> steev: got a sec?
<steev> chrs_: hi
<steev> sure
<chrs_> some questions coming :)
<chrs_> what distro are you running on your chromebook?
<steev> chrs_: gentoo
<steev> also Kali
<chrs_> do you have opengl es support?
<steev> chrs_: yes
<steev> well, yes on gentoo, no on kali
<chrs_> is it hardware support or software support via mesa?
<steev> it's a mixture - you need either xorg 1.12 or 1.13
<steev> and then you need their opengles libraries
<steev> and then you need to use their xf86-video-armsoc git repository (NOT linaro's)
<steev> http://git.chromium.org/gitweb/?p=chromiumos/overlays/board-overlays.git;a=blob;f=overlay-daisy/media-libs/mali-drivers-bin/mali-drivers-bin-1.20-r123.ebuild;h=6b0a675b0324daaa0d67c7c0b36838358c7a6ad3;hb=HEAD just replace ${PVR} with 1.20-r123 to get the .bin file to extract the opengles libraries
<steev> http://git.chromium.org/gitweb/?p=chromiumos/third_party/xf86-video-armsoc.git;a=summary is their git tree for the video driver
<chrs_> hmm
<chrs_> i should i have that stuff installed
<chrs_> i think
<steev> chrs_: or if you're on gentoo, you can use my github.com/steev/arm overlay just switch to the dev branch to pull in the proper mali-drivers-bin, xorg-server and xf86-video-armsoc
<chrs_> interesting
<chrs_> i may end up doing that because i can't get my opengl es stack properly working
<steev> chrs_: if you do, you also need to have an xorg.conf snippet to use the armsoc driver (xorg defaults to fbdev on arm)
<chrs_> can you post your xorg.conf?
<chrs_> i'm not using gentoo but i'll switch to it
<steev> steev@rose ~ $ wgetpaste /etc/X11/xorg.conf.d/20-armsoc.conf
<steev> Your paste can be seen here: http://bpaste.net/show/124349/
<steev> Your paste can be seen here: http://bpaste.net/show/124348/
<steev> steev@rose ~ $ wgetpaste /etc/X11/xorg.conf.d/10-synaptics-chromebook.conf
<chrs_> that's it? just one section?
<steev> chrs_: yes, notice the path
<steev> everything else is defaults from the xorg auto configuration itself (i.e. i have no /etc/X11/xorg.conf)
<chrs_> i didn't either
<chrs_> i created one to stop glx from loading
<chrs_> or try to anyway
<steev> chrs_: if you have a 32gb sdcard
<steev> i have an image up at http://steev.net/distfiles/chromeos iirc
<steev> yep, that's the url - the .img.xz - extract that, write it to a 32gb card, and bob's your uncle
<chrs_> i do have a 32gb sd card
<steev> i should do a newer one but i'm being lazy currently (also read working on other things)
<chrs_> i was hoping to install onto the internal storage though
<steev> the newer install i have is done on the internal storage
<steev> p1 has the nv-uboot, p2 has vmlinux.uimg, p3 is root and p12 has the boot.scr.uimg
<chrs_> do you still have the chromeos files?
<steev> hm?
<steev> no, i completely replaced what is on eMMC
<chrs_> oh ok
<chrs_> how would you get chromeos back if you wanted to?
<steev> the SPI nor is still the chrome one
<steev> so their uboot boots
<steev> and then loads the nvuboot
<chrs_> ok
<steev> and that uboot then loads my kernel
<chrs_> what is the output when you run 'es2_info'?
<chrs_> thats some info from my system
<steev> chrs_: that's really old
<steev> the .45 drivers
<chrs_> ooh..
<steev> so if you've got a newer kernel
<steev> it isn't gonna work as they modified something kernel side that requires newer drivers
<steev> and i forgot to install mesa-progs on this install, let me do that
<steev> and it looks like i forgot to switch to mali so once mesa-progs installs i'll restart x
<chrs_> ok cool
<steev> or not. hrm
<steev> i've been working on building a system completely devoid of opengl
<steev> to fix things that look for opengl when we only use opengles
<chrs_> the mali gpu doesn't support opengl
<chrs_> only opengl es
<chrs_> but it does have hardware accel for opengl es
* WarheadsSE needs to eventually retry on Arch
<steev> chrs_: yes, that's why i'm fixing it to not install anything opengl
<steev> where it = mesa, xorg, mesa-progs
<steev> and pretty much anything else that needs opengl
<steev> i just saw the other day there was a 2012 GSOC project for Blender to run on OpenGL ES
<chrs_> so you're using mesa for opengl es now?
<chrs_> i don't think the opengl es apps will run over mesa
wingrime has quit [Read error: Operation timed out]
<steev> chrs_: correct, that's why gentoo has eselect
<steev> eselect opengl set mali, startx
<steev> done.
<chrs_> wow
<chrs_> i've never used gentoo
<steev> it's not for everyone
<steev> and i cheat because i have a bunch of arm boxen, so i build binpkgs of everything
<chrs_> i only have one :(
<chrs_> i'm not including my iphone or ipod
<chrs_> were you able to run es2_info yet?
<steev> no, i have to fix mesa-progs to not require opengl first
<steev> which is gonna take me a bit of time
<chrs_> how are you going to do that?
<steev> patch out the opengl bits if opengl isn't required?
<chrs_> sounds tricky
<steev> not really
<steev> but it's not a top priority
<steev> i'm far more interested in fixing chromium 30 to build with vfpv3-d16
popolon has quit [Ping timeout: 268 seconds]
<chrs_> whats vfpv3-d16?
<chrs_> when i run es2_info i get
<chrs_> Error: eglInitialize() failed
<chrs_> i guess my opengl es driver isn't isntall properly...
<chrs_> ldd `which es2_info` isn't showing missing libs
<steev> mfpu
<steev> it's mostly for machines that don't have a neon unit
<steev> so marvell and tegra2
<steev> but there are some boards out there with a broken neon unit as well (efika to2 boards)

<chrs_> steev: let me know if you get it working
<chrs_> be interested in checking out what you did, and recreating
<steev> chrs_: which?
<steev> fixing mesa-progs?
<chrs_> the opengl es
<chrs_> yeah
<steev> i'd push the patches into my overlay as i always do, so others can use it
<chrs_> oh ok cool
<steev> i'm not a dick like the linaro guys and hide everything in launchpad
<chrs_> lol
<chrs_> steev: where should i start reading to learn how to install gentoo onto internal storage on the arm chromebook?
<steev> chrs_: i've not posted it anywhere
<steev> i think i did a pastebin of it
<steev> lemme see if i can find it
<steev> chrs_: http://bpaste.net/show/124380/ its' rather terse as it expects people to be somewhat familiar with gentoo
<chrs_> ok
<chrs_> i should probably read up on gentoo first
<chrs_> since i wasn't even familiar with some of the terms you were using earlier
<chrs_> thanks
<steev> chrs_: well it's all built from source
DonkeyHotei has left #arm-netbook ["This is a /part message."]
<chrs_> well, except for the binary mali opengl es drivers
<chrs_> or any other binary drivers i'm not aware of
<chrs_> but i get your point
<chrs_> it's different system from where i'm coming from
<steev> chrs_: well, the only difference there is that it copies the files into place, and makes it switchable in the gentoo way of doing things
<chrs_> ok
<chrs_> i'm a little scared that i have to partition things myself
<chrs_> i'm not sure i want to blow away chromeos at this point
<steev> haha
<chrs_> the ubuntu script i'm using to install chromeos (i've busted the system a nubmer of times and reinstalled) lets me keep chromeos on a small 1gb partition
<steev> well
<steev> the way i do it, worst case you can always plug in the restore chromeos usb and replace everything
<chrs_> i thnk it's 1gb, might be 2
<steev> also can just use an sdcard
<chrs_> the restore chromeos usb?
<chrs_> i got this machine off craigslist
<chrs_> i don't think it came with a "restore usb"
<steev> which is what i did until i was ready
<steev> at some point i'll remove the screw to make the NOR read-write and write the u-boot to it
<chrs_> you have a restore chromeos usb stick that came with the machine?
<chrs_> i guess installing to this 32gb sd would be better than nothing
<steev> chrs_: you can download a restore image
